I Letters PatentN0.-83,991, dated NovemberlO, 1868.

Be it known that I, J. K. Nansen, of Green Point, in the county of Kings, and State of New York, have invented a new and useful Improvement in Divided Car-Axles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawin s, form- Figure .3, a transverse section of the same, taken 4 through the line 27a;

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in the novel construction of a divided car-axle with revolving central boxing, having an oil-receptacle attached to and communicating therewith, and with removable collars or tie-rings arranged therein for preventing separation of the joint, whereby auni-forin lubrication of the journal bythe renewed application of the lubricant at every revolu- 'tion of the boxing is effected, and whereby provision is made for the removal of worn collars, and the substitution of new ones wi'tl1ont incurring the expense of supplying entirelynewiboxiug.

In order that others 'ni'ay understand the construction and operation of my invention, I'will proceed to describe'it with reference to the drawings.

A is a car-axle, carrying upon its extremities a pair of carwheels, B B, of the ordinary construction, and rigidly attached to the axle in the usual way. Said axle A is composed of two parts, or is divided transversely at its centre, and the inner ends thereof, which may be designated as an, are supported within a box, 0. Said box 0 is of suihcient length and strength for the proper support of the said inner extremities a a of the divided axle A, and is made to clasp firmly, or is otherwise ligidly attached to one of the said-inner extremities, as a, so as to revolve by meansof the rotation of the same, while the opposite portion or section, a, of the said axle is permitted to turn'loosely therein, so as thereby to provide for. the variation in the velocities of the inner and outer wheels while running over curves in the road. Upon the portion of the box O which contains the loose portion or section a of the axle, is an'anged a receptacle, D, for containing oil or other lubricating-substance or material. Said'receptools 1) is provided with openings d d, the one for the pouring in-of the oil or lubricant, and the other for the insert-ion and removal of suitable absorbent material, designed tor absorbing and retaining the said lubrican when necessary for preventingthe too free lubrication of the joint; It is also provided with communicatingopenings, 0, which conduct the lubricating-material into the box, at every revolution of the same. Arranged within the said box A is any desirable number of removable collars or tie-rings, e. Said collars or rings care fitted within annniar spaces or grooves formed around the axle, partly within the axle and partly within the box, for the purpose of retaining the axle within the box, and are constructed of two parts, for the more ready application thereof to said spaces or grooves around the axle. I These collars or rings 0, sustaining the full force 'of all diverging or outward tendency of the wheels, soon become worn,

whereupon they may be removed upon the opening of the box, and their places refilled by new ones, thereby avoiding the expense of new boxing, an expense which cannot be avoided by the use of the ordinary divided axle, having said collars attached as a fixture thereto, or to the boxing thereof.

f is a collar, composed of leather, or other flexible or yielding material. Said collar f is fitted within a groove, out within the box 0, at a point near the ex-' tremity of that portion thereof which contains the, loose. section a of the axle, so as to fit closely around the said axle, and is designed for retaining the oil within the box, and prevent the unnecessary Waste of the same;

What I claim as my invention, and desire to have secured-by Letters Patent, is-

The divided car-axle A, constructed as described, with the revolving self-lubricatingbox O, removable collars c, and flexible collar j; substantially as and for the purpose herein set forth.
